Application filed March 10, 1913. Serial No. 753,199.

To all finito/m.- v't may concern Be it known that l', CARL A.lllfvrsoN, a citizen of the United States, residing at l'iynn, in thecounty of Essex and State of ltflassachusetts, have Vinvented new anduseful Improvements in Sectional l-leel-lldge Finishing and llurnishingTools, of which the following is a specification.

rlhis invention relates to a rotary tool adapted to linish or bnrnishthe edges of the heels of boots and shoes either by the wax treatingoperation or by burnishing the edges of said heels after they have beencolored with a suitable coloring material, 1

The object of the invention is to provide a tool which will apply waxevenly to the edges of the heels of boots and shoes and which will alsoimpart a rubbing and pol-l ishing and bnrnishing action to the edges ol.said heels of boots and shoes that are held against it.

Moreover, it the object of this invention to provide ay tool of thecharacter set forth which will have a yielding metallic periphery andwhich will. thus accommodate `itself to the different curves of theedges of boot and shoe heels.

Furthermore, ,it is the object of this invention to provide a tool ofthe elmracter set forth which shall he cheap to manufacture and durablein its constrluztion.

in wax treating the heels of boots and shoes by means of my improvedtool, the wax may be applied in a melted condition to the periphery ofthe tool and the super fluous wax removed therefrom by means of ascraper as described and set forth in my apljilication Serial No.734,507, tiled December i2, 1912, or the wax may be applied by n'leansof a stick held against the periphery of the tool or in any of thevarious .vays in which wax has heretofore been applied to the surface ofa work-rubbing tool in this art. lt is desirable, in addition to rubbingthe heel circumferentially thereof in the wax treating operation, toalsosiniultaneously rub the heel transversely thereof toward the top lift,and it is the object of this invention to provide a tool which shall.perform such an operation upon the edges of boot and shoe heels whichare applied to its periphery. lt is also very desirable, in a tool ofthis character, that the periphery of the rotary tool shall be flexibleand capable of assuming ditl'erent forms in cross sectional cont-our inorder to [it the varying contours of the edges of boot and shoe heelswhich may be applied thereto.

in addition to wax treating the edges of boot and shoe heels by means ofmy iinproved tool, the saine may be used as a burnishing tool pure andsimple, that is, it may be used to impart a high luster to the edges ofthe heels of boots or shoes and can be utilized without the wax it sodesired, in which ease a coloring material is employed, such asblacking, and the burnishing tool is then utilii/.ed to polish orburnish the edge of the heel with this coloring material thereon. Ineither ease, whether by wax treating or by burnishing a colored heel, myimproved burnishing tool imparts a, high luster and smooth tinish to theedge of the boot or shoe heel which is applied to it, and imparts saidluster to the entire surface of the boot or shoe heel, irrespective ofthe varying forms of said heel or slight inequalities in the surfacethereof.

'lhe invent ion, therefore, consists in a heel bnrnishing and finishingtool such as described in the following specification and particularlyof the construction forth in the claims.

Referring to the drawings: Figure 1 is a plan view of a portion of amachine for wax treating, burnishing and finishing the edges of theheels of boots and shoes with my i1nproved heel burnishing tool attachedthereto, the parts being broken away to save space. Fig. i). is asectional elevation taken on line Q 2 of Fig. l, also broken away tosave space7 a heel being shown in dotted lines in the proper positionrelatively thereto. Fig. 2% is a detail view of one of the segmentalblocks with a portion of the helical member upon which the blocks aresupported shown in connection therewith.

Li ke numerals refer to like parts throughout the several views of thedrawings.

Vla the drawings, 5 is a frame having a bearing t' in which is rotatablymounted a shaft 7 to which is attached a pulley 8 by means of which saidshaft is rotated. My improved heel burnishing and finishing tool 9 isat-tached to the front end of said shaft. and embodies a hub 10 which isfastened by a set-screw 11 to said shaft 7.

The rim 12 of the tool 9 is formed by a flexible member, preferablyconsisting of a metallic strip or Wire 13 forming a helix, one end ofsaid helical member 13 being fastened, preferably by Welding, to a ring14, the other end of said helical member being fastened to an annularflange 15, which flange is fastened by means of screws 16 to acylindrical flange 17 forming a part of the hub 10, and upon thishelical member is mounted a series of blocks 24 Which are adapted torock laterally on the helical meinber 13 by reason of being pivotedthereto by means of the ears 25 provided at opposite ends of said blocksand extending inwardly therefrom. rlhese ears are formed on the arc of acircle concentric With the center of the Wire forming the helical member13, so that said blocks can rock upon said helical member and assumedifferent positions according to the shape of the edge of the heel whichis being burnished or finished by said tool, the cross sectionalcontourrof the periphery of the tool thus being in the form of apractically continuous curve and fitting nicely the curve of the heelthroughout its entire height. The ring 14 fits in an annular recess 18provided in a flange 19 and is fastened thereto by means of screivs 20.The cylindrical flange 17 is provided with an annular recess 21 toreceive and center the flange 15. The flange 19 is provided with a hub22 and is adjustably fastened to the hub 10 by means of a set-screw 23.The rim 12, consisting of the helical member 13 and the segmental blocks24, is thus fastened to a holder, said holder consisting of the hub 10,the flanges 15, 17 and 19 and the ring 14. It Will thus be seen that therim 12 constitutes the periphery of the tool 9 and is supported upon theholder hereinbefore described, Which holder is fastened to the shaft 7by the set-screw 11 and is rotated therewith. The adjacent co-nvolutionsof the helical member 13, with the segmental blocks 24 mounted thereon,are prevented from lateral movement relatively to each other by theflanges 15 and 19 and the ring 14 and in practice said blocks are heldpractically in contact With each other. By adjusting the Harige 19tovvard the flange 15, it will be seen that the different segmentalblocks 24 may be clamped against each other.

The relative proportions of the parts are such that a space 26 isprovided in the finishing tool between the inner faces of the segmentalblocks and the ange 17, which thus allows the different convolutions ofthe helix and the blocks mounted thereon to yield or move inwardlytoward the median .axial line of. the tool 9 Without abutting againstsaid cylindrical flange 17.

Suitable means fol1 heating the tool 9 is provided such as the gas pipe27. 1t Will be seen that the rim 12, therefore, presents a yieldingmetallic periphery and also that said periphery is resilient, by reasonof the Wire 13 being formed of spring metal. The bloclrs 24 arepreferably made of metal, but it will be evident that any material whichis hard as compared with leather can be utilized for said blocks, solong as the material of which the blocks are made is sufficiently 'hardto polish or burnish leather When a continuous and smooth curveextending across the periphery of said rim by reason of the blockstipping to adjust themselves to such positions that their outer surfaceswill form portions of the desired curve or of the curve of the heelWhich is being burnished or finished. 1

is the member 13 is formed asia helix, it is evident that when the tool9 is rotated there will be a polishing action extendingcircumferentially of the edge'of the heel and also a tendency to lay thefibers of the leather smoothly, by reason of the action of the helicallydisposed blocks 24 Which thus stand at an angle and tend to rub the edgeof the heel from the heel seat toward the top lift.

The cross sectional contour of the rim 12 upon its outer surface is madeso as to be convex in its normal form, and when a heel having a straightedge or having a curved edge of lesser degree than the curve upon Whichthe periphery of said rim is formed is being burnished or finisheduponmy improved burnishing tool, the different convolutions of the helix andthe block mounted thereupon forming the periphery of the tool, willyield so that the periphery of the tool will yield and conform to theedgev of the heel which is being linished thereon.

1n usine the tool of my invention, the shoe is placed against it in theusual manner and Where Wax is utilized it is supplied to the tool by anysuitable means, as hereinbefore set-forth, so that an even coat of Waxis placed upon the edge of the heel and thoroughly burnished andpolished thereon, said heel afterward being subjected to the action of apadding roll and a brush to obtain a liner polish in a manner Well knownto those skilled in this art. The tool being heated by a jet of gas orother suitable means keeps the wax is a liquid condition while it isbeing applied to the heel.

Having thus described my invention, what lA claim and desire by Letterslatent to secure is:
